title: Scintigraphic, spirometric, and roentgenologic effects of radiotherapy on normal lung tissue. Short-term observations in 14 consecutive patients with breast cancer.
abstract: The effects of radiotherapy on lung function, ventilation/perfusion scans, and chest radiography were studied prospectively in 15 patients who underwent either modified radical mastectomy or tumorectomy, followed by radiotherapy for breast cancer. In all patients, pulmonary function studies, chest x-ray films, and lung scintigraphic studies were performed prior to and at the end of radiotherapy as well as three months later. No consistent or significant alteration in either parameter was detected. No patient developed clinical symptoms suggestive of radiation-induced lung changes, although in one of them, major radiologic features were found that were consistent with radiation pneumonitis; those changes disappeared completely in the course of the subsequent months. It is concluded that the tangential beam technique for postoperative irradiation as used in these patients is largely safe as regards pulmonary function, perfusion, and ventilation.
